Description

Intelligent mattress automatic adjustment control method, control system, storage medium and mattress Technical Field

[0001] The present invention relates to the field of bedding products, and in particular to an automatic adjustment control method, a control system, a storage medium and a mattress of an intelligent mattress. Background Art

[0002] Since sleep accounts for nearly one-third of our lives, and with rising living standards, people's expectations for mattresses are increasing. To ensure mattresses meet these requirements and ensure a more relaxed and restful sleep, mattresses are often equipped with various sensors and video surveillance equipment to monitor a person's posture. The height of different parts of the mattress is then adjusted to best fit the body's curves, promoting stress relief and relaxation. However, these sensors are wearable and must be worn, compromising comfort and convenience. Video surveillance equipment also hinders privacy protection. Using a sampled pressure matrix method to detect body posture is expensive, making it unsuitable for widespread application. Summary of the Invention

[0003] The purpose of the present invention is to solve the above-mentioned problems existing in the prior art and to provide an intelligent mattress automatic adjustment control method, control system, storage medium and mattress. The automatic adjustment control method enables the mattress to detect changes in the body's lying posture in a timely manner and make adjustments, so that the mattress can always fit the curve of the human body, provide comprehensive and effective support for the human body, and help improve the body's relaxation and rest quality.

[0004] The above technical objectives of the present invention are mainly solved by the following technical solutions:

[0005] The automatic adjustment control method of an intelligent mattress is characterized by:

[0006] Step 1: When the user initially lies on the mattress, the initial air pressure of each airbag is automatically adjusted to obtain the air pressure judgment reference value A, and the initial parameters of the air pressure of each airbag and the trigger flag value are set;

[0007] Step 2: Sample the air pressure of each airbag in real time and obtain the average air pressure S of each airbag during the sampling period;

[0008] Step 3: Determine the value of SA to determine whether the body is in motion or in a stable state. If it is motion, modify the trigger flag value and return to step 2. If it is in a stable state, proceed to step 4.

[0009] Step 4: Update the air pressure judgment reference value A and air pressure parameters of each airbag, and determine the trigger flag value;

[0010] Step 5: Determine the body stabilization time. If the stabilization time is reached, adjust the air pressure of each airbag; otherwise, return to step 2.

[0011] Step 6: Repeat steps 1 to 5 to automatically adjust the air pressure of each airbag.

[0012] Through the above steps, the mattress can detect changes in the body's lying posture in time, and adjust the air pressure of each airbag, change the hardness and height of the airbag, so that the corresponding part of the mattress can always fit the curve of the human body, provide comprehensive and effective support to the human body, and help improve the body's relaxation and rest quality.

[0013] As a further improvement and supplement to the above-mentioned technical solution, the present invention adopts the following technical measures: In step 2, when sampling the air pressure of each airbag in real time, a sampling cycle is set, the number of samples within the sampling cycle is set, sampling is continued for the duration of the set sampling cycle, and the sampled air pressure is averaged to obtain the average air pressure S. When a person lies still in bed, the supporting airbag is subjected to downward pressure from the body's weight. The value of the pressure sensor = the initial airbag pressure + the body pressure. When a person changes their posture due to movements such as turning over, sitting, or lying down, the detected air pressure value of the corresponding airbag also changes. The posture state is calculated based on the changing trends of the airbag pressure values ​​and the changing trends of the combined airbag pressures, paving the way for subsequent adjustments to the airbag pressures.

[0014] As a preference, in order to be able to more accurately measure the average air pressure S, the mattress accurately responds to the corresponding action, so that the air pressure value of each air bag is appropriate, and the human body is reasonably and appropriately supported, which is beneficial to protecting the spine and making the human body comfortable. , n is the number of samples in a sampling period, n ≥ 50. The average pressure S is the average airbag pressure over a period of time, which is used to obtain the pressure change during the period and thus determine the user's body movements during the period.

[0015] Preferably, in step 1, the initial parameters include a maximum air pressure threshold Pmax, a minimum air pressure threshold Pmin, and a trigger flag value F of 0 (F=0 indicates that the body is stable before that moment, and F=1 indicates that the body is moving before that moment, i.e., body movement). The maximum air pressure threshold Pmax is used to detect whether the human body is moving or not. The minimum air pressure threshold Pmin is used to determine whether the human body is in a stable state. When it is detected that the airbag air pressure change value is greater than the maximum air pressure threshold Pmax, the trigger flag value F is changed to F=1. When it is detected that the human body is in a stable state, the trigger flag value F remains F=0.

[0016] Preferably, in step three, when the airbag pressure condition is SA≥Pmax, the trigger mark value F=1 is modified, the clock is called, and the process returns to step two; when Pmin<SA<Pmax, the process returns to step two; and when SA≤Pmin, the process proceeds to step four. That is, when it is detected that the airbag pressure change value is greater than or equal to the maximum pressure threshold Pmax, it indicates body movement, the trigger mark value F=1 is modified, the clock is called, and the process returns to step two to continue sampling, which is used to monitor the end of body movement and body stability, and to facilitate the adjustment of the airbag pressure to adapt to the pressure conditions of various parts of the body in the current stable state and provide appropriate support. When it is detected that the airbag pressure change value is less than the maximum pressure threshold Pmax, the process continues to determine whether the airbag pressure change value is less than or equal to the minimum pressure threshold Pmin. If the airbag pressure change value is less than the maximum pressure threshold Pmax and greater than the minimum pressure threshold Pmin, it indicates that the body is stable, and the process returns to step two to continue sampling. If the airbag pressure change value is less than or equal to the minimum pressure threshold Pmin, the process proceeds to step four.

[0017] Further preferably, in step 3, when SA ≥ Pmax, the clock T is called, where T = T1 and T1 = 0. This is used to determine the duration of the stable state after the body movement and stabilization, and is used to adjust the airbag pressure. If the duration is insufficient, the process returns to step 2 and continues sampling. If the duration meets the requirement, the airbag pressure is adjusted.

[0018] Preferably, in step four, the value of S in step three is assigned to A, Pmax and Pmin are updated, and the trigger flag value F is judged. If F=1, it means that body movement has occurred before, and the process goes to step five; if F=0, it means that no body movement has occurred before, and the process returns to step two.

[0019] Preferably, in step five, the body stability duration is T=T1+t1, where t1 is the time of a judgment cycle, t1=50ms~100ms. When T≥10s, the air pressure of each airbag is adjusted, and the trigger flag value F is assigned to 0. When T<10s, the process returns to step two. When the body is in a stable state for a duration of T=T1+t1, the air pressure of each airbag is adjusted to adapt to the current posture of the body's stable state and provide appropriate support for the body. At the same time, the trigger flag value F=0 is modified, and the process returns to step two to continue sampling. If the body is in a stable state for an insufficient duration, it indicates that the air pressure of each airbag cannot be adjusted, and the process needs to return to step two to continue sampling.

[0020] Preferably, there are at least four airbags, which support the shoulders, back, waist and buttocks respectively. The initial air pressure of each airbag is P01, P02, P03, P04 respectively.

[0021] Then A=(P01+P02+P03+P04) / 4,Pmax=(10-A) / A 2 ,

[0022] Pmin = (10-A) / (10* A 2 ).

[0023] Another technical subject of the present invention is a control system, which is characterized in that the control system executes the above-mentioned automatic adjustment control method of the smart mattress, and the control system includes:

[0024] A support module, used to support the user's airbag;

[0025] The monitoring module monitors whether the user moves on the mattress and obtains user movement information and air pressure information of the airbag;

[0026] The processing module receives the air pressure change value obtained by the monitoring module and calculates the average air pressure S within the sampling period for automatic adjustment of the airbag pressure;

[0027] The storage module is used to store the corresponding data, corresponding formulas and air pressure comparison process processed by the processing module;

[0028] The adjustment module receives the trigger signal from the processing module to adjust the air pressure of the airbag.

[0029] In the control system involved in this technical solution, the processing module is mainly used to execute and process the automatic adjustment control method of the intelligent mattress, generate a trigger signal for automatically adjusting the air pressure of each airbag, so that the intelligent mattress can achieve the purpose of automatic adjustment.

[0030] Preferably, the processing module uses the air pressure judgment reference value A, the maximum air pressure threshold Pmax, the minimum air pressure threshold Pmin, the trigger mark value F and the call clock timing T to analyze the air pressure situation SA in the airbag and send a trigger signal.

[0031] Another technical subject of this technical solution is a storage medium, characterized by storing a computer program that, when executed by at least one processing module, implements the aforementioned intelligent mattress automatic adjustment control method. The storage medium forms a memory module, providing the processing module with the program and data required for operation, ensuring continuous system operation and ensuring that the threshold for excessive bed exit is correlated with the user's daily habits.

[0032] Another technical theme of the present technical solution is: an intelligent mattress, including a cushion body, characterized in that: the cushion body is provided with at least shoulder airbags, back airbags, waist airbags and hip airbags, respectively used to support corresponding parts of the human body when lying on the mattress, and each airbag can be filled with gas of a certain air pressure value; the cushion body is equipped with the above-mentioned control system, and the control system executes the above-mentioned intelligent mattress automatic adjustment control method to automatically adjust the air pressure of each airbag.

[0033] Specifically, a monitoring module is also provided on the cushion body, and the monitoring module is connected to the processing module signal, and the processing module is connected to the adjustment module signal. In actual application, the adjustment module is an inflation and deflation device, and the monitoring module is used to monitor the air pressure information. The processing module processes the air pressure information to form control information, and the adjustment module receives the control information to control the inflation and deflation device to inflate or deflate, so that the air pressure of each airbag is automatically adjusted.

[0034] The smart mattress involved in this technical solution automatically adjusts the air pressure of each airbag in the mattress (the airbags include at least shoulder airbags, back airbags, waist airbags and hip airbags) by running the smart mattress automatic adjustment control method through the control system, so that each airbag reaches a corresponding hardness and height, thereby achieving the purpose of the mattress fully supporting the human torso and the human spine, which is conducive to human relaxation. In addition, when the human body has not moved for a long time, the air pressure of each airbag can be automatically adjusted, causing the surface curvature of the mattress to change, allowing the human body to change posture according to the surface condition of the mattress, thereby improving the smoothness of blood circulation in the human body and benefiting human health.

[0035] In order to make the control box highly integrated and avoid the scattered distribution of various components, which is convenient for installation, maintenance and replacement, the inflation and deflation device includes an air pump, a solenoid valve for controlling the air pump, and the air pump is connected to each airbag through a pipeline. The air pump, solenoid valve and processing module are all arranged in the control box.

[0036] The present invention has the following beneficial effects: 1. The automatic adjustment control method is adopted so that the mattress can detect the changes in the lying posture of the body and make adjustments in time, so that the mattress can always fit the curve of the human body, provide comprehensive and effective support to the human body, and help improve the relaxation and rest quality of the body. 2. According to the user's lying posture and the support force required by each part of the body, the inflation volume of the airbags in the mattress that provide support force is automatically adjusted to reach a suitable air pressure value, so that the pressure on the human body is balanced, and adaptive adjustments can be made in real time during sleep and rest, improving the degree of curvature of the human spine, which is not only conducive to improving the relaxation and rest quality, but also conducive to correcting the body's bad posture. 3. For people who lie in bed for a long time, during the bed monitoring process, the airbags can be set to automatically inflate or deflate, and the body posture changes accordingly, so as to achieve the purpose of adjusting the body position from time to time, which is conducive to maintaining smooth blood circulation in various parts of the body.

[0042] The technical solution of the present invention will be further specifically described below through embodiments and in conjunction with the accompanying drawings.

[0043] Example 1: This example provides a method for automatically adjusting and controlling a smart mattress.

[0044] As shown in FIG1 , the steps of an automatic adjustment control method for an intelligent mattress are as follows:

[0045] Step 1: When the user initially lies on the mattress, the initial air pressure of each airbag is automatically adjusted to obtain the air pressure judgment reference value A, and the initial parameters of the air pressure of each airbag and the trigger flag value are set;

[0046] Step 2: Sample the air pressure of each airbag in real time and obtain the average air pressure S of each airbag during the sampling period;

[0047] Step 3: Determine the value of SA to determine whether the body is in motion or in a stable state. If it is motion, modify the trigger flag value and return to step 2. If it is in a stable state, proceed to step 4.

[0048] Step 4: Update the air pressure judgment reference value A and air pressure parameters of each airbag, and determine the trigger flag value;

[0049] Step 5: Determine the body stabilization time. If the stabilization time is reached, adjust the air pressure of each airbag; otherwise, return to step 2.

[0050] Step 6: Repeat steps 1 to 5 to automatically adjust the air pressure of each airbag.

[0051] Through the above steps, the mattress can detect changes in the body's lying posture in time, and adjust the air pressure of each airbag, change the hardness and height of the airbag, so that the corresponding part of the mattress can always fit the curve of the human body, provide comprehensive and effective support to the human body, and help improve the body's relaxation and rest quality.

[0052] In this embodiment, the mattress is adjusted in real time with the changes in the body, without causing discomfort such as restraint to the human body or affecting personal privacy, as in the prior art, by wearable sensors. This avoids the discomfort such as restraint to the human body and does not affect personal privacy.

[0053] In other words, according to the user's lying position, the different weights of different parts of the body are pressed on the mattress, generating pressure. The pressure is detected by the detection sensor, and the inflation volume of each air bag in the mattress used to provide support is automatically adjusted according to the pressure detection situation, so as to achieve adaptive adjustment of the user's real-time sleeping feeling. It is used to adjust the human body's good and correct posture, which is beneficial to maintain or improve the degree of human spinal curvature. At the same time, for people who lie in bed for a long time, it provides an effective reference during the bed rest monitoring process, and automatically assists in posture adjustment through the inflation and deflation of the air bags, which is beneficial to smooth blood circulation and balanced pressure on various parts of the human body.

[0054] For further optimization, in step 2, when sampling the air pressure of each airbag in real time, a sampling cycle is set, the number of samples within the sampling cycle is set, and continuous sampling is performed within the set sampling cycle duration. The sampled air pressures are averaged to obtain the average air pressure S. When a person lies still in bed, the supporting airbag is subjected to downward pressure from the body's weight. The pressure sensor value = the initial airbag pressure + the body pressure. When a person changes their posture due to movements such as turning over, sitting, or lying down, the detected air pressure value of the corresponding airbag also changes. The posture state is calculated based on the changing trends of the airbag pressure values ​​and the changing trends of the combined airbag pressures, paving the way for subsequent adjustments to the airbag pressures.

[0055] Further optimization is required to accurately measure the average air pressure S so that the mattress can accurately respond to corresponding actions, so that the air pressure value of each airbag is appropriate, and the human body is properly supported, which is beneficial to protecting the spine and making the human body comfortable. , where n is the number of samples in a sampling period, n ≥ 50. The average air pressure S is the average airbag pressure over a period of time, which is used to obtain the air pressure changes during the period and thus determine the user's body movements during the period.

[0056] Further optimization: In step 1, the initial parameters include the maximum pressure threshold Pmax, the minimum pressure threshold Pmin, and the trigger flag value F of 0 (in this technical solution, F=0 indicates that the body is stable before that moment, and F=1 indicates that the body is moving before that moment). The maximum pressure threshold Pmax is used to detect whether the human body is moving. The minimum pressure threshold Pmin is used to determine whether the human body is in a stable state. When the airbag pressure change value is detected to be greater than the maximum pressure threshold Pmax, the trigger flag value F is changed to F=1. When the human body is detected to be in a stable state, the trigger flag value F remains F=0.

[0057] During use, when the user initially lies on the mattress, the initial air pressures of the shoulder airbag 2, back airbag 3, waist airbag 4 and hip airbag 5 are set to P01, P02, P03 and P04 respectively according to user needs. When the human body is in a stable state, the air pressures of the shoulder airbag 2, back airbag 3, waist airbag 4 and hip airbag 5 reach the set values. At this time, the curvature of the human spine is small, the human body is most stretched, and it is most conducive to relaxation.

[0058] Further optimization: In step 3, when the airbag pressure condition is SA ≥ Pmax, the trigger flag value F is modified to 1, the clock is called, and the process returns to step 2. When Pmin < SA < Pmax, the process returns to step 2; when SA ≤ Pmin, the process proceeds to step 4. That is, when the airbag pressure change is detected to be greater than or equal to the maximum pressure threshold Pmax, it indicates body movement. The trigger flag value F is modified to 1, the clock is called, and the process returns to step 2 to continue sampling. This is used to monitor the end of body movement and body stability, allowing for adjustment of the airbag pressure to adapt to the pressure conditions of various body parts in the current stable state and provide appropriate support. When the airbag pressure change is detected to be less than the maximum pressure threshold Pmax, the process continues to determine whether the airbag pressure change is less than or equal to the minimum pressure threshold Pmin. If the airbag pressure change is less than the maximum pressure threshold Pmax and greater than the minimum pressure threshold Pmin, it indicates body stability, and the process returns to step 2 to continue sampling. If the airbag pressure change is less than or equal to the minimum pressure threshold Pmin, the process proceeds to step 4.

[0059] For further optimization, when SA ≥ Pmax, the clock T is called, where T = T1 and T1 = 0. This is used to determine the duration of the stable state after the body movement and stabilization, and is used to adjust the airbag pressure. If the duration is insufficient, the system returns to step 2 and continues sampling. If the duration meets the requirement, the airbag pressure is adjusted.

[0060] The above scheme is further improved. In step 4, the value of S in step 3 is assigned to A, Pmax and Pmin are updated, and the trigger flag value F is judged. If F=1, it means that body movement has occurred before, and the process goes to step 5; if F=0, it means that body movement has not occurred before, and the process returns to step 2.

[0061] Further optimization, in step five, the body stabilization duration T=T1+t1, where t1 is the time of a judgment cycle, t1=50ms~100ms, when T≥10s, the air pressure of each airbag is adjusted, and the trigger flag value F is assigned to 0, when T<10s, return to step two.

[0062] When the body remains stable for a duration of T = T1 + t1 (e.g., T reaches 10 seconds), the air pressure of each airbag is adjusted. The air pressure adjustment strategy outputs adjustment targets Pm1, Pm2, Pm3, and Pm4, such that Pm1 = Pm2 = Pm3 = Pm4 = S, to adapt to the current body's stable posture and provide appropriate support. The trigger flag value F is changed to 0, and sampling is continued in step 2. If the body remains stable for a short duration, it indicates that the air pressure of each airbag cannot be adjusted, and sampling needs to be continued in step 2.

[0063] Further refine the above technical solution, there are at least four airbags, which support at least the shoulders, back, waist and buttocks. The initial air pressure of each airbag is P01, P02, P03, P04 respectively.

[0064] A=(P01+P02+P03+P04) / 4, Pmax = (10-A) / A 2 ,

[0065] Pmin = (10-A) / (10* A 2 ).

[0066] In summary, for ease of understanding, the above control methods are listed and described as follows:

[0067] S101: The airbag is divided into four areas according to the structure of the human spine: shoulder, back, waist and hip. P01, P02, P03 and P04 are the initial air pressure values ​​when the user initially lies on the mattress (at this time, the curvature of the human spine is small, and P01, P02, P03 and P04 are relatively close values). The airbag can withstand the air pressure range (in this solution, it can be set to 0.5kpa~10Kpa).

[0068] S102: Initialize the pressure reference value A for user action determination, which is (P01+P02+P03+P04) / 4. Since airbag deformation decreases as pressure increases, the pressure difference caused by the same intensity also decreases. Based on the airbag's characteristics, the action determination threshold is determined. The maximum airbag pressure is limited to less than 10 kPa. The maximum action pressure determination threshold, Pmax, is set to (10-A) / A2; the minimum action pressure determination threshold, Pmin, is set to (10-A) / (10*A2). The trigger flag, F, is set to 0.

[0069] S103: The airbag pressure changes according to the amplitude of the user's movement. In order to detect the change, a high-precision AD sensor (of course, an ADC sensor is also applicable) is used to sample the air pressure at a period of 50ms.

[0070] S104: Calculate the average air pressure of the user for 5 consecutive seconds.

[0071] , n is the number of sampling periods within 5 seconds.

[0072] S105: The user's movement is judged in real time based on the sampled values, and the movement reaching a certain intensity (SA ≥ Pmax) is used as the starting point for judgment execution. If the user's movement does not reach the certain intensity, jump to S107.

[0073] S106: When the user's movement reaches the judgment condition (SA≥Pmax), the trigger flag value F=1 is assigned, indicating that the body movement has started, and the timer T is called at the same time, and T=0 at this time.

[0074] S107: The user's movement is determined in real time based on the sampled values. The starting point for the determination is when the movement reaches a certain intensity (SA ≤ Pmin), indicating that the user has stabilized. If SA is greater than Pmin at this point, the process returns to S103.

[0075] S108: If the body has entered the stable stage, update the body movement judgment intensity Pmax, Pmin and the air pressure judgment reference value A, assign the value of S to A, and update Pmax and Pmin.

[0076] S109: Determine whether the trigger flag value F is equal to 1. If F=1, it means that body movement has occurred, and continue to proceed. If F=0, it means that no body movement has occurred, and return to S103.

[0077] S110: The timing starts from the moment when the user begins to stabilize (SA≤Pmin) after the user has made body movements. After each judgment cycle meets the conditions for T to increase effectively, T increases by one judgment cycle time t1.

[0078] S111: Wait until T is greater than or equal to 10s, indicating that the body movement is completely stable, and proceed to the next step. If T is less than 10s, return to S103.

[0079] S112: According to the change of the air bag pressure and the characteristics of the human spine in the prone position, adjust Pm1=Pm2=Pm3=Pm4=S.

[0080] Example 2: As shown in FIG4, this embodiment provides a control system, which is used to execute the automatic adjustment control method of the smart mattress involved in Example 1, so that the smart mattress can achieve the purpose of automatic adjustment.

[0081] The control system of the automatic adjustment control method of the intelligent mattress includes: a supporting module for supporting the air bag of the user, a monitoring module for monitoring whether the user moves on the mattress and obtaining the user's body movement information and air bag pressure information, as well as a processing module, a storage module and an adjustment module.

[0082] The processing module receives the air pressure changes acquired by the monitoring module, calculates the average air pressure S during the sampling period, and analyzes the air pressure SA in the airbag using the air pressure reference value A, the maximum pressure threshold Pmax, the minimum pressure threshold Pmin, the trigger flag value F, and the timer T. It then sends a trigger signal to enable the adjustment module to automatically adjust the airbag pressure. The storage module stores the corresponding data, corresponding formulas, and air pressure comparison process processed by the processing module. The adjustment module adjusts the airbag pressure upon receiving the trigger signal from the processing module.

[0083] Embodiment 3: This embodiment is a storage medium for storing a computer program for executing the method for automatically adjusting and controlling an intelligent mattress described in embodiment 1.

The storage medium forms a storage module that provides the processing module with the program and data required for operation, ensuring the continuous operation of the control system. The smart mattress can adaptively adjust its support surface to the curve of the human spine, providing real-time, effective, and reliable support for the user's body, facilitating efficient relaxation and rest.

[0085] Embodiment 4: As shown in FIG2 and FIG3, this embodiment provides a smart mattress.

In addition, when the human body has not moved for a long time, the air pressure of each airbag can be automatically adjusted, causing the surface curvature of the mattress to change, so that the human body changes its posture according to the surface condition of the mattress, thereby improving the smoothness of blood circulation in the human body and benefiting human health.

[0089] In order to make the control box 7 highly integrated and avoid the scattered distribution of various components, which is convenient for installation, maintenance and replacement, the inflation and deflation device includes an air pump, a solenoid valve for controlling the air pump, and the air pump is connected to each airbag through a pipeline.
